The Challenge

The Houston-Galveston region represents one of the largest areas of land-surface elevation change, or subsidence, in the United States. Most of the land subsidence in this region has occurred as a direct result of groundwater withdrawals for municipal supply, commercial and industrial use and irrigation. A web-based tool for exploring how groundwater, sediment compaction, and land-elevation change are related is needed to help resource managers make informed decisions on water usage.

Our Solution

IHDS developers created a two-part web application that included:

• Designing a single page application to explain subsidence research in the gulf coast
• Building a web map viewer to explore data collected from the last 40 years
• Continuing to add additional data, such as PAM data, into the existing web application
